TLV320AIC3106IRGZR

The TLV320AIC3106 is a low-power stereo audio codec with stereo headphone amplifier, as well as multiple inputs and outputs programmable in single-ended or fully differential configurations. Extensive register-based power control is included, enabling stereo 48-kHz DAC playback as low as 15 mW from a 3.3-V analog supply, making it ideal for portable battery-powered audio and telephony applications.

The record path of the TLV320AIC3106 contains integrated microphone bias, digitally controlled stereo microphone preamplifier, and automatic gain control (AGC), with mix/mux capability among the multiple analog inputs. Programmable filters are available during record which can remove audible noise that can occur during optical zooming in digital cameras.
